RE: help needed for mazda protege 96 1.8l doch modification
you will need to rebuild the motor with forged rods and pistons. the pistons will need to be dish top pistons for lower compression. you will need a fuel and engine management system. there are two options with that, stand-alone and piggy back. if you aren't running larger injectors, you could run a unichip piggy back. this unit is pretty basic and plug-and-play as they get as long as the injectors don't get changed. if you swap the injectors, you may want to go with stand-alone.
